As far as I am aware of, this IS the current design model.
The parts that concern me (if I didn't mention) is the part of the AF that actually drove the AF group of elements. I do not think that a belt type system is a long term reliable way to go on that. Stretching, slipping... too many moving variables for myself to enjoy not thinking about it. I know I have to keep this in perspective, this is not an 11K 400mm. But all glass should be a solid investment. Bodies come and go... glass is almost forever.
I have done quite a few repairs here at home for people from, doing LCD replacements, Rubber, Dust/Clean/Lube lenses, switch replacements etc.. And although I've not had to enter the belly of this beasty, from what I have read about it in comparisons with the stator/rotor (lack of a better term) on the SWM design of Nikon, and theirs.. I'm just too leery to make that recommendation as this as a reasonable purchase.
I keep picturing everything in my life I've ever had a rubber band on (I live for putting rubber bands on everything). Now not to say this is in fact rubber. It could be some polymer belt, or, some other concoction they've taken up. But I'm a BMW direct drive kinda bloke. So for all of those reasons -- I'd be out.

no referenced readings to suggest? also, should your radio call-name be "rubber band man"?
